What is the maximum response time of AT+QICLOSE, AT+QISEND and AT+QIRD
In the manual it is not mentioned, only " / " shown.

2

UDP is connectionless. Theoretically, its return is very fast

4

After sending “AT” command we will receive the “RDY”
or if we just power OFF and ON then automatically we’ll receive “RDY”

in some module it is mentioned that “PB DONE” will come but I’m not receiving any of those

5

PB DONE needs to be output after the UE registration network is completed, and RDY indicates the module to boot up and initialize

6

Can you send me the AT command sequence
for INITITIALIZATION

neccesary commands

7

I’m using EC200U Series
Revision : EC200U-CNAAR03A03M08

Does “PB DONE” will come in older version??

8

No, it will be printed out on all versions

9

There is no AT command to query its initialization status
